I noticed this for some companies: there are 10+ spreadsheets which should have the same structure, but different data. For example one spreadsheet per country for purposes of budgeting, modeling, or just inputs. These spreadsheets tend to break and it’s hard to update them centrally. There is of course an option with moving to a proper admin app, but it requires development and quite often results in less UX, because users are familiar with spreadsheets - they can write formulas, analyze the data, or connect with other systems.

This is why I’m writing a tool to simplify administrative work with these files, so you can quickly see where spreadsheets diverge, propagate updates, make them version controlled, and many other good things, which we have in typical app development, but still miss in spreadsheets management.
